Inadvertently putting their own family at risk is just part of the job? So Trump can have his photo op and otherwise disregard CDC guidelines? WTF, Tsing?
Again, you haven't defined risk. I don't believe the agents feel they are being put at risk. I don't believe it either.
If an agent's healthy demographic says they have a .0001 chance of dying from COVID and that happens to be the CFR for their demographic with the flu (I am just making up numbers to prove a point) then there's no additional risk to the event than any other event any other President has hosted during the course of their tenure.
